Frequently Asked Questions

Can I Use Other Types of Soda Instead of Baking Soda?

While baking soda is the most popular and effective type of soda for cleaning a microwave, some people may wonder if they can use other types of soda instead. The answer is yes, but not all types of soda will provide the same results as baking soda.

Aluminum-based soda, such as sodium bicarbonate, is the most common type of soda used for cleaning. However, other types of soda, such as seltzer or club soda, may not be as effective due to their lower pH levels. Additionally, these types of soda may contain added flavors or sweeteners that could leave a residue in the microwave.

If you do not have baking soda on hand, you can try using white vinegar as an alternative. White vinegar is a natural cleaning agent that can help to break down and remove grease and grime in the microwave. Simply mix equal parts water and white vinegar in a microwave-safe bowl, microwave for a few minutes, and then wipe down the interior of the microwave with a damp cloth.
